Hello Dennis, Thank you for responding. I think we are chasing 2 different Capt John Grahams. Your Capt John appears to me to be of either the line of Genl Joseph Graham or Col William Graham of NC Rev War fame.
The 1824 Huntsville, Ala notice of death for Capt. John Graham, age 71 "in this county" (means Madison Co, Ala, not Lawrence Co) . . .numbers his descendants, 11 children (6 sons & 5 daughters), etc.
That notice makes that Capt. John Graham (b) 1753. Your John Graham who gave knowledge of Capt John Nelson works out to a date of birth 1759 (age 73 in 1832).
I have located in the 1830 and 1840 census(s), Monroe Co, Ala the John H. Graham that I'm trying to make the link between Isaac Nelson Graham (b) 1828 Ala, [father (b)SC, mother (b) SC], and possibly Capt John Graham listed 1790 census Berkeley Co, Charleston District, St James Goose Creek Parish, SC.
This is logical to me because that John H. Graham is buried in the oldest known grave in Angelina Co, TX. My Isaac Nelson Graham came to that area (enroute 1860 census).Child born TX 1861.He founded a long line of Grahams who settled and stayed in Angelina Co, TX.
There was also the line of a Dempsey Graham in Angelina Co TX about the same time.
Anyway, we'll see how this shakes out. Thanks again, Dennis Peggy
